T (ill whom it may concern:

Be it known that I, CHARLES E. WARWICK, a citizen of the'United States,residingat Vicksbui' in the county of Warren and State of 'ssissippi,have invented certain new and useful Improvements in Grease I Guns, ofwhich the following is a specithe Wheels of the cars come into fication.I This invention has relation to certain new and useful improvements v1ngrease guns,

and has for its primary object the provision,

provision of a special form of shoe for thegrease gun to properly applythe oil or grease tothe rail.

Wish the above and other objects in view, the invention resides in thenovel construction, combination, and arrangement of parts as-hereinafterset forth in the specification, pointed out in the claims, and'shown inthe drawings, in which- Figure 1 is an elevation of the complete devicein use; Fig. 2 is an elevation at right of the device engaged with arail; Fig. 3 is an enlarged elevation with the shoe and the rail insection.

Referring more particularly to the drawings in which similar referencecharacters designate corresponding parts throughout the several views, 1designates the cylinder or-body of the device adapted to contain the oilor grease to be applied to the rail 2, said cylinder or bodyl havingapiston 3- mounted therein upon the threaded piston rod 4which hasmovement through the head 5 secured upon the outer end or upper end ofsaid cylinder or body 1. It will be understood that a suitable operatingwheel 6 is mounted upon the outer end of the threaded piston rod 4 torevolve the latter and therebymove the piston 3 in said cylinder or body1.

A feed pipe has one end secured in the conical lower end 8 of thecylinder or body 1, while its opposite end is threaded in the .grea'sesupplying shoe 9 and it will be evident that as the piston 3 is forcedtoward the lower end of said cylinder or body 1, the oil or grease willbe forced downwardly through the feed pipe 7.

The shoe 9'is bifurcated to form tongues 10 and 11 for engaging therespective upper and side faces of the head or tread portion of the rail2. The tongue 10 is flat to rest upon the upper face of the rail 2, asshown in Figs. 1 and 3 of the drawings and extends at an acute angle tothe main portion of the shoe 9, while the tongue 11 is curved. as shownin Figs. 1 and 3, and positioned at about right angles'to the tongue 10,thereby forming an oilor grease pocket 12 to the side of the rail 2 andabove the point at which the tongue 11 is engaged with said rail 2. Oilor grease is conducted from the feed pipe 7 to the oil or grease pocket12 by the oil or grease conducting passage 13,'while the second oil orgrease conducting passage 14 serves to conduct oil or grease from thefeed pipe 7 to the upper face of the rail 2. The

oil or grease conducting passages 13 and 14 are separated by a suitablepartition 15 riding upon the upper edge of the rail 2 when the device isin operation. a

When thin oil or grease is used, the oil or grease conducting passage 13may be closed, if desired, in order that the thin oil or grease may beapplied only to the upper face of the rail 2 at gage line and thenproperly distributed by the tongue 11 of the angles to Fig. 1 showingthe lower portion shoe 9. When a thick or heavy oil or grease is used,however, it may be desirable to close the passage 14 in order that theheavy oil or grease may be directed only to the side of the rail treadbefore being distributed by the tongues 10 and 11 of the shoe 9. It willalso be understood that the ends of the tongues 10 and 11 may be curvedupwardly, if desired, to permit the device to readily slide over lips injoints or guard rails. It will further be seen that by providing thispocket 12, the gravity or flow of the oil or grease keeps this pocketfilled and thereby causes a continuous supply of oil or grease to the Itwillbe readily seen that the shoe 9. tongue 10 serves only as a rider toguide the shoe on the top tread of rail, while the tongue 11 is extendedto do all of the spreading. This will prevent grease being applied tothe top of the rail and causing a collision.

While the preferred embodiments of the invention have been shown anddescribed, it

details of construction, and arrangement of parts may be resorted towithin the scope of the appended claims without departing from thespirit of the invention or sacrificing any .of the advantages of thesame.

What is claimed is:

1. A grease gun comprisinga shoe, rail engaging tongues carried b saidshoe and positioned at an angle to t e latter and to one another, saidshoe and tongues being arranged to form a pocket to one side of saidrail when said tongues are engaged therewith, a lubricant feed pipeconnected with said shoe, said shoe having separate conducting passagesformed therein to conduct a lubricant from said feed pipe to said pocketand to the upper face ofsaid rail, and means for supplying a lubricantto said feed pipe.

per e ge of said curved tongue, a lubricant feed pipe connected withsaid shoe, said shoe having opposltely extended separate passages formedin its central portionand leading from said feed pipe to the-workingface of the straight tongue and the pocket whereby the lubricant will beconducted to both,

rail with which said tongues are faces of the engaged.

' In testimony whereof I afiix my signature of two witnesses.
